5 Things to Know About Synthetic Urine

The idea of synthetic urine is pretty simple: take real urine, add some chemicals to it, and voila — you have synthetic urine. It is a subject of many online debates, but in reality, synthetic urine is commonly used by people looking to pass a drug test. Some people use it as an alternative to being caught using drugs. And for some people, using synthetic urine can be their only option. 

As with drug testing, many employers require that their employees pass a urine drug test before they’re allowed to work. If this is you, you might wonder what the best way to pass a drug test is—and whether synthetic urine can help you do that? 

Luckily for you, we’ve compiled a list of five things that you should know about synthetic urine. 

It’s becoming increasingly difficult to pass a drug test. 

As technology improves, the drug labs get better at detecting fake urine, so it’s becoming harder to pass. The industry recognizes this and has made it more difficult for people to cheat on their tests. 

Go for the best synthetic urine products online. Some fake urine purchased in stores is of inferior quality compared to what you can buy online from reputable companies. 

The best brands have complete formulas that mimic real human urine. Doctors developed them using purified water, urea, creatinine, pH balance solutions, and uric acid. It’s virtually identical to human urine; it looks like it, smells like it, and even has the same density as natural human urine. 

You must use high-quality synthetic urine because of today’s advanced labs. 


Synthetic urine is pre-mixed and ready to use. 

Synthetic urine is pre-mixed and ready to use, but it must be heated in a microwave or in hot water to achieve the correct temperature.  

The human body maintains the temperature of its urine between 90-100 degrees Fahrenheit (32-38C), so your synthetic sample must be heated within this range. If it is too cold, testers will know that it is synthetic; it may burn the tester if it is too hot. You can check the temperature of your sample with a thermometer before submission. 

If you do not have access to a microwave or hot water source, there are also products on the market that allow you to adjust the temperature of your synthetic sample using heat pads. 

It has a normal pH level, specific gravity, and creatinine levels.  

Creatinine is one of the most common ingredients in natural urine produced by our muscles. It is, therefore, a standard component in all synthetic urine samples. Its pH level is similar to natural urine, and the specific gravity is between 1.002 and 1.030. Having these key components in the right proportion ensures that synthetic urine can be used as a substitute for natural human urine during drug tests by labs. 

It’s sterile, so no bacteria or other microorganisms will be present in it, as they may be present even in high-quality samples of human urine. 

Synthetic Urine is Both Safe and Legal. 

Another thing you should know is that synthetic urine is safe and legal to use. Many people associate synthetic urine with illegal drugs, but it’s not as bad. This product is usually associated with “fake pee” or “synthetic piss,” but these are slang terms for the substance. It’s chemically formulated in a lab to mimic human urine in all aspects except smell and color.  

As mentioned above, it has the same pH, specific gravity, creatinine, and uric acid levels as real human pee. So, if you are using it in a laboratory setting, no one will be able to tell the difference between real pee and your fake pee sample unless they run a complete chemical analysis on it — which most labs do not do! 

Each of the different synthetic urine brands is slightly different from the others.  

Some synthetic urine works for most situations, but some will only work for certain types of drug tests. Some products have a pre-mixed liquid inside of them. This often works for all situations because they look just like real human urine, and they have all of the same compounds in them. 

If you want to make sure that the synthetic urine will pass a drug test, you need to make sure it has everything that real human urine has in it. Things like urea, uric acid, and creatine need to be present in synthetic urine to pass as human urine during a drug test. 

You can buy kits online and learn more about how they work before using them. 


We hope we’ve cleared up some confusion surrounding synthetic urine and keep you up to speed on some of its benefits. While it may not be the right choice for everyone, it may be a good alternative if you’re in a tight spot or have a lot on your plate and need an extra helping hand.
